POLISHING-WHEEL.

Specification of Letters Patent.

Application led. February 15, 1906.

Patented June 8, 1909.

Serial No. 301,119.

To all whom it may concern.'

Be it known that I, HECTOR E. MorNEAU, a citizen oi' the United States, residing at Vorcester, in the county ol' Worcester and Commonwealth ol' Massachusetts, have invented a new and useful Improvement in Polishing-Wheels, of which the following is a specification, accompanied by drawings l'orming a part of the same, in Which-- Figure 1 is a side view of a machine having a polishing wheel embodying my invention. Fig. 2 is a central, vertical, sectional view of my improved polishing wheel, and Fig. 3 is a sectional view on line 3 3, Fig. 2.

Similar reference figures refer to similar parts in the dierent views.

My invention relates to a polishing wheel for polishing the heels of boots and shoes, and comprises an improved method of obtaining the necessary degree of heat on the rim of the polishing whee to keep the waxed cloth at the proper temperature to accomplish the polishing, and it consists in the construction and arrangement oi' parts as hereinafter described and pointed out in the annexed claims.

Referring to the accompanying drawings 1 denotes the n'frame of the machine, 2 the shaft of the polishing Wheel ournaled in the bearing 3 in the frame 1 and driven by the pulley 4 and belt 5. Held on the end of a shaft 2 by a set screw 6 is a hollow polishing wheel 7 of the usual shape, and upon the rim 8 of the wheel 7 the waxed cloth 9 is stretched, as is usual in machines of this class. The waxed cloth 9 is held upon the rim 8 in any convenient manner common in wheels oi this class. The polishing wheel 7 is preferably provided with a removable side 10, attached byscrews 11, 11, and having a hollow hub 12 through which is inserted a burner 13 connected by suitable pipes 14 and 15 with a source o1' gas supply not shown.

It has been found that the products of combustion from the burner 13 do not readily escape frorn the hollow polishing wheel, and that it is, in fact, difficult to maintain a continuous combustion of gas from the burner 13. To attain this object, I provide the hollow hub 12 with a fan 16 having the outer ends of its blades attached to the inside o'f the hollow hub 12, and the inner ends connected with a hub 17 which revolves around the pipe 14. The blades oi' the fan 16 are arranged at an oblique angle to their plane of rotation, so that as the i'an 16 is re- 18 having openings 19 for the admission of air in the usual manner in burners of this class.

I preferably form a series of holes 2O through the hub of the polishing wheel on the side opposite the fan 16, for the better circul ation of air through the interior chamber of the polishing wheel, but other openings may be provided if desired.

What I claim as my invention and desire to secure by Letters Patent is 1. In a hollow polishing wheel, the combi-y nation with a burner inserted in the interior of said wheel, of means for maintaining a current of air into the interior of said wheel, and means for the escape of the products of combustion from said wheel.

2. The combination with a hollow polishing wheel having a concentric opening on one side and means for rotating said wheel, ol' a burner inclosed in said wheel, and a fan in said opening arranged to rotate with said wheel, with said wheel also provided with a second opening.

3. The combination with a hollow polish'- ing wheel having a concentric opening in one side and means for rotating said wheel, of means for maintaining a circulation of air into and out of the interior of said wheel.

4. The combination with a hollow polishing Wheel having a concentric opening in one side, an opening distinct from said concentric opening and means for rotating said wheel, of a burner inclosed in said wheel, means for supplying fuel to said burner, and a series of blades held by said wheel in said concentric opening.

Dated this rst day of February 1906.
